Abstract:
An enclosure including an upper frame, a lower frame, and a lift mechanism operably coupling the upper frame and the lower frame together. The lift mechanism includes first drive shafts and a second drive shaft operably coupling the first drive shafts for operation in unison, and an input operably coupled to at least one of the first drive shafts or the second drive shaft. The lift mechanism transitions the enclosure between a stowed state and a deployed state during a movement of the actuator.
